Strange, powerful signals from deep space called fast radio bursts are slippery little suckers.

Most of them just flash once, a mysterious huge spike in the radio data out of nowhere, lasting just milliseconds at most. They can’t be predicted, and because they’re so brief, they’re incredibly hard to trace.

Hard; but not impossible. Less than a year ago, for the first time, astronomers announced they traced one of these mysterious one-off signals to its source galaxy. Since then, their techniques have allowed them to trace three more.

Mars — glorious, dusty, complex Mars — may once have been even more dazzling. New research provides even more evidence that a rubbly ring once circled the Red Planet.

The new clue lies in Deimos, the smaller of the two Martian moons. It’s orbiting Mars at a slight tilt with respect to the planet’s equator — and this could very well be the result of the gravitational shenanigans caused by a planetary ring.

Ring systems aren’t actually all that uncommon. When you think about ring systems, your mind immediately leaps to Saturn, no doubt — but half the planets in the Solar System have rings, Saturn, Uranus, Neptune, and Jupiter. Dwarf planet Haumea, and centaurs Chiron and Chariklo also have rings.

NASA is monitoring an asteroid that may be as large as the Empire State Building, expected to pass Earth on Saturday, June 6.

Asteroid 2002 NN4 is estimated to be 250–570 meters (820–1,870 feet) in diameter, according to NASA’s Jet Propulsion Laboratory (JPL). New York City’s iconic Empire State Building is more than 1,400 feet tall at its tip.

The asteroid may seem daunting, but it will pass Earth at a safe distance, a representative for JPL told CBS News.

Discovery Sheds New Light on Famous Einstein Ring

Social distance science made possible with public W. M. Keck Observatory and NASA archive data.

Determined to find a needle in a cosmic haystack, a pair of astronomers time traveled through archives of old data from W. M. Keck Observatory on Mauankea in Hawaii and old X-ray data from NASA’s Chandra X-ray Observatory to unlock a mystery surrounding a bright, lensed, heavily obscured quasar.

NASA began exploring this idea in 2018. At the heart of this technology is a structure that gives mushrooms its shape — mycelium. These structures, which grow into mushrooms, are sturdy and flexible.

Ordinarily, planning a mid-afternoon launch from Florida during the summer would be inadvisable, especially if there’s no margin for error. The heat and humidity can make for “dynamic” weather conditions (to use a word that came up frequently in forecasts last week) that make it difficult to predict if a launch can proceed.

However, the schedule for the Demo-2 commercial crew mission was dictated not by Mother Nature but instead by Isaac Newton. The launch was tied to the orbit of the International Space Station so that the Crew Dragon spacecraft could reach the station after launch. That required an instantaneous launch window that, in late May, happened to be in the afternoon from the Kennedy Space Center.

Still, try explaining that to the boss. “I was told that the rocket you just witnessed had to be launched within one second, or it would be impossible for it to hit its target,” President Donald Trump said last Saturday, after a successful launch that he watched in person. He had been at the Kennedy Space Center three days earlier as well, when weather conditions didn’t quite clear in time to allow the launch.
